History of San Juan

In 1783, San Juan was partitioned from Santa Ana but was still a barrio within the Province of Manila. The opening salvo of the Philippine Revolution against Spain took place in San Juan in 1897 when the Katipunan attacked the alamacen (armoury) or polvorín (gunpowder magazine) of the Spanish East Indies colonial government. The town was later incorporated into the Province of Rizal in 1901 under American Occupation.

On 7 November 1975, President Ferdinand Marcos signed Presidential Decree № 824 that established the National Capital Region, and San Juan was among the towns excised from Rizal Province. Residents ratified the conversion of the municipality into a highly urbanised city on 16 June 2008, pursuant to Republic Act № 9388 ("An Act Converting the Municipality of San Juan into a Highly Urbanized City to be known as the City of San Juan"). Then Congressman Ronaldo B. Zamora sponsored the Cityhood Bill in the House of Representatives and worked for its approval.

Presidential ties

Although not officially designated as such, San Juan is noted to be the "Town of Philippine Presidents." Four presidents since the Third Republic were official residents of San Juan when they assumed office. They were the Macapagal père et fille, Diosdado Sr. (1961–1965) and Gloria Arroyo (2001–2010); Ferdinand Marcos (1965–1986); and Joseph Estrada (1998–2001), who also served as Mayor when San Juan was still a municipality
